Fixed In:

Opened: Dec 21, 2016
Severity: 2-Critical


The asm_config_server_rpc_handler daemon may panic, leaving a core file. The process will be restarted by the system.


The asm_config_server_rpc_handler works upon only internal information; the resulting brief interruption has no effect on data-plane traffic handling.


During some kinds of disruptions of normal processing (for example, an high availability (HA) failover), the control-plane daemon responsible for keeping the ASM policies in sync may mishandle an internal message, triggering an internal logic fault.


None known.

Fix Information

The asm daemon no longer cores under these conditions.
